Nociceptor-specific gene deletion reveals a major role for Na _v 1.7 (PN1) in acute and inflammatory pain

Abstract excerpt

Nine voltage-gated sodium channels are expressed in complex patterns in mammalian nerve and muscle. Three channels, Na(v)1.7, Na(v)1.8, and Na(v)1.9, are expressed selectively in peripheral damage-sensing neurons. Because there are no selective blockers of these channels, we used gene ablation in mice to examine the function of Na(v)1.7 (PN1) in pain pathways. A global Na(v)1.7-null mutant was found to die...
